Web Access to Long-term Research Hydrology Data Doug Ryan USDA Forest Service Research and Development
The Needs • Watershed scale information • Needed to address many issues • A few examples: • Post-fire risks • Watershed restoration/rehab • Fish passage
Advantages of Research Data • Precisely measured • Quality controlled • Small watersheds • Supporting data available (metadata) • Land use known and/or controlled • Many other aspects studied
Watershed Cross-Comparison Post & Jones (2001)
Long-term Data Exist • Experimental watershed studies • In many parts of country • High quality data • Many variables measured/controlled • But access has been difficult • Needed: One-stop, easy access
Individual Site Central Site Public User Relational Database CGI Script Harvester Solution: HydroDB “Centributed” Mechanics (Baker et al. 2000 BioScience) Monthly Data (V-One,V-Many) CGI Script Dynamic URL Site Database Daily Data Static URL Graphics Local Script Exchange filters Exchange format Report formats Distribution filters
Beta version of web harvester • http://www.fsl.orst.edu/hydrodb/index.htm • Primarily developed for data input • Next phase will improve public access
Next Goals • Improve user-friendliness • Add tools to use long-term data: • Fish passage • Post fire risk • Roads/culvert design • Add other kinds of observations • Suggestions?
Conclusions • Long-term hydrology important • Web-access now possible • More development needed: • Add more types of observations • Add tools to use this gold mine
